Maskera
Mask Personal Data Before It Reaches Your AI.
Maskera finds and masks names, personal identity numbers, addresses and phone numbers in text, before it is used in AI systems, logs or analytics tools. Built for Swedish text and Swedish personal data.

Where Maskera Fits
AI Systems
Send prompts and documents to AI models without leaking names, personal identity numbers or contact details.
Logs
Keep your logs useful for debugging, minus the personal data.
Analytics
Feed analytics and BI tools with text that is free of personal data.
How It’s Built
Self-Hosted by Default
Maskera is installed on your side and the text stays on your side. No cloud dependencies, no third party in the flow.
Built for GDPR
Masking personal data early is data minimization for real: less data to protect, fewer systems in scope.
Simple to Integrate
A straightforward API that fits the flows you already have: before the AI call, before the log write, before the export.
Inspect It Yourself
The core of Maskera is open: the code is on GitHub, the package on npm and the NER model on Hugging Face. You don’t have to take my word for how it works, you can read it and run it before you talk to me.

How accurate is it? That’s for the pilot to answer, not a sales deck. I run pilot projects with companies and organizations in Sweden. Get in touch and I’ll show you what it looks like, or read more at maskera.dev.
